Provided herein is a linear programming-based algorithm to estimate the clock skew in network delay measurements based on one-way delay measurements. The algorithm has the time complexity of O(N), leaves the delay after the skew removal positive, and is robust in the sense that the error margin of the skew estimate is independent of the magnitude of the skew. The algorithm is understood to be unbiased, and the sample variance of the skew estimates is small.
